Learn
how toquickly check your car’s health from the color of the smoke emitted by your
car exhaust – Tips from Partsavatar Aftermarket Parts.
You can easily
determine an auto malfunction from the smoke emissions. It is definitely time
to pay attention to your car if you notice smoke of different colors emitting
from exhaust tailpipe.
Not all type of smokes
determine auto malfunction. In some cases, if you notice a large amount of
smoke coming out of car exhaust pipe,
you would more or less consider that something is wrong with your car’s engine.
But it is to be noted that it is not always the same case. Not all automotive
problems can be detected from smoke types. But still, how do you know that the
smoke is ruining your engine? When do you think is the time to visit the
mechanic once you notice smoke?
Parts Avatar gives you
the answer. In this article, we shall differentiate between different colored
auto smokes that you must be familiar with along with their causes.
What
are the Causes of Smoke?
First and foremost let
us know why the smoke is produced before analyzing different colors of smoke.
If there is some problem with the engine that produces smoke, that smoke makes
its exit through the exhaust.
Sometimes, fire under
the hood produces engine smoke and in the worst case flames may start coming
out which could lead to a disaster. Do yourself a favor and get far away from
your car if you notice something like this. It is foolish decision to keep on
driving as it will eventually become risky for your safety.
Oil dripping from
leaking valve cover gasket into the hot manifold may also produce smoke. You will
also notice oil pooling under the car or the driveway if the leak is large.You
can replace car valve cover gasket
under aftermarket prices which are quite cheap.
So, not always there is
issue with engine. But to begin with, smoke is not a good sign. Hand over your
car to a certified technician and let him figure out what to do. Now let us
discuss causes of different colored smoke emitted out of exhaust.
White
Exhaust Smoke
Sometimes small amount
of condensed vapors come out of exhaust in the form of white smoke. It is not
that dangerous though. Vapors quickly dissipate in the atmosphere after exiting
car exhaust tailpipe. But if your
car is producing frequent thick white smoke, then it might be alarming.There is
possibility that coolant might be burning inside the internal combustion
chamber. There are various causes behind this as follows.
Cylinder
Head
As the combustion chamber
is located in the cylinder head, most explosive processes take place in here.Engine misfires
are always caused due to cracks in cylinder head.
The crack in the cylinder head
causes the coolant to enter the combustion chamber.
Due to too much heat
inside the chamber, overheating can be caused. Due to immense heat, a lot of
stress is put on cylinder head. As the cooling system has already failed and
pressure has been built, this whole scenario causes the head gasket to
malfunction and the cylinder head starts to crack. When the mixture of coolant
and fuel is burnt for combustion process, it produces white smoke.
Auto Cylinder heads are one of the car’s
costly repairs. Your car may need complete replacement of cylinder head. If the
cylinder heads are ignored, by time the damage is so big that you might need to
consider buying a new car.
Blown
Head Gasket
The basic purpose of
head gasket is to seal the block and the cylinder head. Often a damaged head
gasket or cracks in the engine block makes passage for the coolant to enter the
combustion chamber and get mixed with the fuel. Thus white smoke is produced. car's engine Head gaskets
are cheap to purchase but at the same time costly when it comes to the labor.
Cracked
engine block
A crack in the deck of
engine block near the coolant jacket will cause the coolant to enter the
combustion chamber.Cracked engine block can become a grave problem for your
car’s engine. It is virtually impossible to repair a cracked engine block.
Engine block supports almost all the components of the engine.
A crack in the block
will cause huge leakages making your car emit white smoke. It is better to get
an engine replacement as a whole.
It is to be noted that
emission of white smoke is the first sign of engine overheating problem.Overheating of engine
can lead to massive auto component damage under the hood. So call your mechanic
immediately.
Gray/Blue
Exhaust Smoke
A malfunctioning
turbocharger or burning of oil in the combustion chamber can cause the exhaust
to emit blue smoke.You might need to replace turbocharger of your car
if it is faulty.These are possible symptoms.
Transmission
fluid leakage
The transmission fluid
used by your vehicle’s transmission might be leaking and getting mixed with the
oil or fuel and getting burnt. A malfunctioning transmission vacuum modulator
may be the culprit here which is causing the leakage and burning.
Leaking
Valve stem seal
The valve stems
regulate the oil to lubricate the guides in the chamber. Grey emissions might
be produced due to faulty stem seals as they make the way for the oil to enter
the combustion chamber. The best way is to either replace Auto Valve stem seal set or
just replace the engine if the damage is quite big. Worn or damaged piston rings,
damaged valve guides also cause grey smoke to be emitted out of the exhaust.Replace
car's piston rings in combustion chamber
too.
Stuck
PCV Valve
Blue or gray smoke
could also be produced due to immense crankcase pressure caused by the stuck
PCV Valve. Stuck valve may cause oil leakage into the chamber thus producing
grey fumes. If they are loose, tighten PCV Valve of car and check whether the
smoke persists. Otherwise call your mechanic for better advice.
Black
Exhaust Smoke
Burning of excessive
fuel in the engine often causes the black exhaust smoke to emit. This means
that too much gas is entering the chamber but only small amount of fuel is
being burnt. In this case fill your gas tank with relevant amount of fuel. Let
us take a look at some other causes.
Dirty
Air filter
The air filter allows
the oxygen to enter the combustion chamber and blocks other substances from entering
the chamber. But if it is clogged, less air is allowed in the chamber resulting
in your car burning too much fuel with small amount of oxygen which results in
black smoke. It is better to replace the car air filter if you notice any
symptom of malfunction.
Faulty
Fuel Pressure Regulator
Our car’s fuel system
is designed to work in different range of pressures.The fuel pressure regulator
controls the pressure with which your car runs. A faulty regulator may cause
the pressure to fluctuate and if it falls too low then there may not be enough
fuel reaching the engine to start it. Replace the fuel pressure regulator if
necessary.
Clogged
Fuel injectors
Fuel injectors are the
devices that are used to spray small amount of atomized gasoline into the
vehicle’s Engine intake manifold
which is meant to mix with the oxygen to start your car’s engine. A faulty fuel
injector will cause too much fuel to leak inside the chamber which in turn
produces black smoke. The remedy is to repair the auto fuel injectors.
Fuel
Return
A restricted fuel
return line allows too much fuel to be dissipated for combustion purposes. If
the amount of fuel for combustion is higher than normal, more fuel will be
burnt and the rate of burnt gases leaving the combustion chamber will also
increase resulting in black smoke.
Burning excessive fuel
will affect your car’s fuel economy. So pay attention to what it needs to
ensure more miles for your car.
Bottom
line
If your vehicle is
running on too much oil, engine is burning too much oil or if you notice oil or
coolant leakage, then there is a possibility that your engine is malfunctioning.
Smoke depicts that the
car is in distress. Always diagnose what needs to be repaired and beware of the
fake auto repair shops. Take advice from a professional or even take second opinion.
Don’t wait for the engine light to flash.
Keep an eye on the
smoke emitter by your car’s exhaust and keep proper level of Auto transmission fluid
and coolant of car
in your car.

Troubleshoot
problems, causes and ways to improve oil consumption capacity of your car –
Tips from PartsAvatar Auto Parts.

In this article, you
will get the answers to the questions like, how to determine whether the
consumption is high or low? What is its cause? How to fix it?
How
to determine whether the consumption is normal?
As the vehicles age,
there fuel or oil consumption also increases due to wear. So how much is
considered normal? Let us read it in detail.
Not every engine
consumes same amount of oil because of their different specifications of
engines. There is not a specific guideline for this issue.
BMW tells its customers
that the normal consumption can be in the range of one quart within 2000 miles
on a properly driven or serviced drive. Sometimes answers vary as different
professionals and mechanics have varying views over oil consumption.
So as a uniform rule,
engines with fewer than 50000 miles should not use much more than a quart of
oil between oil changes. Engine might be showing the signs of leaks if it
demands oil every 3000 miles. This could also point to other engine problems
related to combustion, worn out piston rings or worn seals.On the hole you can
expect increase in oil consumption after 75000 miles under normal conditions.
For heavy engines like
V6 or V8, manufacturers permit oil consumption up to 1 liter per 1000 km. many
newer engines use low viscosity oil. This increases the chances of oil
consumption as the thin oil slips over worn out rings, seals and gaskets.
It is very important to
timely check for engine oil level and leaks in the engine. Visit your mechanic
as soon as you encounter any problem regarding oil consumption. If you suspect
leaks, get the element fixed or replaced otherwise the repair cost would be
quite expensive if the damage increases. Consumption also depends upon the type
of driving we do on the road. If you practice moderate driving on the road the
consumption might be 0.1L per 1000 miles.
What
is causing increased oil consumption?
Check the following
symptoms for increased oil consumption.
No
Smoke from Exhaust
If there is no trace of
smoke in the exhaust, there is high possibility that oil level is low.Check the
following root causes in this case.
Check the PCV Valves
and replace them if they are not working properly.
The engine might have
been undergoing some internal mechanical problems so diagnose and fix them
immediately.
If the engine is not
burning the oil properly then there are chances that engine’s
valve seals are damaged. Visit your mechanic and get the
valve seals replaced.
There might be some
issue with engine’s gasket. Sometimes damaged or worn gasket or seals may
increase the oil consumption. Get the gaskets and seals checked and repaired at
the same time by a professional.
Coolant
appears Brownish and foamy
There are many symptoms
here like the most common being dirtied coolant. There aren’t any leaks visible
but still your vehicle is losing oil and the engine is consuming more oil than
normal. If you detect these symptoms then it is better to check the following
causes.
Blown head gasket and
cracked cylinder head are on the top of the list. It’s better to start your
inspection by examining the head gasket and cylinder heads. If you find them
not working up to the mark, then it is the right time to get them replaced. Aftermarket auto head gaskets and cylinder head are quite reliable
and increasingly purchased by most owners.
Sometimes a crack or
leak in the oil line could cause the oil to slip into the cooling system and
ruin it. In this case replace or your car's engine oil cooler.
Oil
puddles under the car
If you notice puddles
of oil under your car, there is probably a leak. The oil level is not proper
and sometimes you may notice burning smell of oil when the engine is idle. Keep
your engine filled with proper level of oil and check for the following reasons
that could prompt these symptoms.
In this case, you might
have to check and replace your engine’s damaged PCV valves if necessary. You
can also visually inspect the engine’s gasket and seals for any sign of damage
or wear.The oil might be escaping due to loosened oil filter. Check car's engine oil filter out and tighten it. If you feel the need of
replacement, then go ahead as it is a very simple DIY job for you.
Engine
uses more oil and there is some smoke in exhaust
There are many symptoms
like the Engine is consuming more oil than normal.The oil level gets low and
engine’s oil is being burnt due to the smoke in the exhaust. If you notice that
your car engine is losing its capacity and power then you will have to check
the following causes.
A clogged PCV valve can
cause the oil get sucked through air intake into the engine. In this case, it
is better to get car's PCV Valve replaced by a professional.
A worn piston ring is a
danger to the engine as it allows the engine oil to slip past. Oil might get on
the wrong side of the ring so call your mechanic immediately if you notice any
damage and replace auto
piston rings if necessary.
Similarly, you will
need to check the valve seals, as they might also be allowing the oil to slip
through where it should not. Get the Valve seals replaced by professional if
you detect this issue.
How
to fix it?
The very first step
towards fixing is to always use good quality oil in your vehicle. It is very
important to maintain the proper level of the engine oil. If you ever notice
oil contamination or carbon deposits on the oil neck, replace
the dirty oil with the new high quality one matching
your engine’s standards.
As explained above, if
you notice the symptom and after detecting the damaged parts, get them replaced
by your mechanic. Not every replacement job is a DIY, so secure your vehicle in
the hands of mechanic or a professional.
For oil leaks there are
some products called stop oil leaks available at online auto parts stores, so
you can also choose this method to stop the leak.
In the end Parts avatar
advises to use premium quality oil and the most important thing is to check and
maintain your car regularly for best performance. You can also check Partsavatar.ca
